This was made clear earlier, but we were also investigating the effects of additives to improve physical properties, particularly toughness. As a result, especially Cr, Go, Ni.
Ｆｅの中の１種以上を添加すると靭性改善効果が著しい
ことを見出し、これらの知見に基づいて本発明を成すに
至った。It was discovered that the addition of one or more types of Fe significantly improves toughness, and based on these findings, the present invention was accomplished.

cubic oxides such as Δalso Oa, Crx03,

There are hexagonal oxides such as Nb205- and 5t02, and the average particle size of these is 2 μm or less, preferably 1 μm.
m or less is better. Further, when the amount of these oxides added is 0.1 to 90% by weight based on the total amount, it has an effect of improving physical properties. That is, if the amount of these components added is less than 0.1% by weight, there will be no effect of addition, and if it exceeds 90% by weight, it will become difficult to densify, leading to a significant decrease in hardness.

There are cubic carbides made of V and Vl group transition metals such as iTa)C, and these carbides have the effect of improving physical properties when added in an amount of 1 to 90% by weight, but have no effect when added in an amount less than 1% by weight. However, if it exceeds 90% by weight, it becomes difficult to densify it, leading to a decrease in physical properties.

ところである。Also, boron carbide added as an additive component is usually 0.1% by weight.
From the above, since it exerts its effect, there is not much point in adding less than 5% by weight, while on the other hand, if the amount added exceeds 5% by weight, the sinterability deteriorates significantly and densification becomes difficult. This fact was previously disclosed in Japanese Patent Application No. 60-082033.

One or more of these should be added in an amount of 0.1 to 40% of the total amount.
When added in an amount by weight, densification becomes easier and the physical properties of the sintered body, especially the toughness, are significantly improved. If the amount added is less than 0.1% by weight, it will not have much effect on densification. If it exceeds 40% by weight, the toughness will increase, but the properties will be significantly different from those of ceramics.
